Using X-ray and Mössbauer methods, structural aspects of iron introduction into the lithium-manganese oxide spinel are studied, and batteries with the lithium anode and the test compound as cathode subsystem are tested. The basic parameters of the crystal structure of LiMn2−yFeyO4 are calculated, and causes for their changes with increasing iron content are established. The results of structural analysis are confirmed by Mössbauer method. As shown, the specific operating parameters of current sources are reduced due to disordering of the cathode active material structure in case of significant alloying with iron.

Key words: spinel, cation substitution, lattice constant, disorder, superparamagnetism.
